This is the first time I've heard of it but to be honest it doesn't sound like such a bad idea. Wouldn't be long before players stopped acting like children around the referee. Only the captain should be protesting these things.
He stated: "The white card is a new initiative. It is related to the behaviour of the football players. Play-acting, criticism on the field, these are not accepted by people who love the game.
"Yellow cards will still exist too but it might be interesting to have another card.
"This white card would send off a player for a few minutes, maybe five or 10. This would be a way to promote the game among fans who don’t want to see this.
"With a white card, there would be no suspension. I think we should learn from other sports, like rugby, who have used this system."
Platini, who was joined in Dubai by Uefa's Chief Refereeing Officer, Pierluigi Collina, also believes that some current laws of the game need to be "simplified" in order to ensure that football remains accessible to as wide an audience as possible.
